Check Digit Verification of cas no

The CAS Registry Mumber 167862-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,8,6 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 167862-24:
(8*1)+(7*6)+(6*7)+(5*8)+(4*6)+(3*2)+(2*2)+(1*4)=170
170 % 10 = 0
So 167862-24-0 is a valid CAS Registry Number.

1,1-Diacyloxy-1-phenylmethanes as versatile N-acylating agents for amines

Chapman, Robert. S.L.,Tibbetts, Joshua. D.,Bull, Steven. D.

, p. 5330 - 5339 (2018)

1,1-Diacyloxy-1-phenylmethanes and 1-pivaloxy-1-acyloxy-1-phenylmethanes have been used as bench stable N-acylating reagents for primary and secondary amines and anilines under solvent-free conditions to afford their corresponding amides in good yield.

The chemistry of acylals. 3. Cyanohydrin esters from acylals with cyanide reagents

Sandberg, Marcel,Sydnes, Leiv K.

, p. 687 - 689 (2007/10/03)

(equation presented) When treated with KCN in DMSO at room temperature, acylals from aliphatic aldehydes gave the corresponding cyanohydrin esters in good to excellent yields. Acylals from aromatic aldehydes were less reactive and gave several byproducts in addition to fair yields of cyanohydrin under the same conditions. Trimethylsilyl cyanide mixed with titanium(IV) chloride afforded cyanohydrin esters in good to excellent yields from both aliphatic and aromatic aldehydes.

The chemistry of acylals. Part I. The reactivity of acylals towards Grignard and organolithium reagents

Sydnes, Leiv K.,Sandberg, Marcel

, p. 12679 - 12690 (2007/10/03)

Aldehyde acylals have been prepared and reacted with Grignard and alkyllithium reagents. Acylals from formaldehyde furnished complex reaction mixtures when reacted with both reagents. Acylals of other aldehydes gave reaction mixtures that consisted mainly of an ester, generated by replacing one of the carboxy groups with the organic part of the organometallic reagent, and regenerated aldehyde. The esters were formed in the highest yields. Yields above 90% were experienced when the acylals were reacted with Grignard reagents under Barbier conditions.
