Check Digit Verification of cas no
The CAS Registry Mumber 142115-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,1 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142115-65:
(8*1)+(7*4)+(6*2)+(5*1)+(4*1)+(3*5)+(2*6)+(1*5)=89
89 % 10 = 9
So 142115-65-9 is a valid CAS Registry Number.

, p. 546 - 555 (2007/10/02)
The reaction of dibromine with the heterocycles I-IV gives corresponding 3,5-dibromo derivatives, while the less selective reactions with dichlorine afforded 3,5-dichloro derivative XII only in the case of 4H-thiopyran IV and trichloro derivative of the p
