Check Digit Verification of cas no

The CAS Registry Mumber 74705-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,0 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74705-62:
(7*7)+(6*4)+(5*7)+(4*0)+(3*5)+(2*6)+(1*2)=137
137 % 10 = 7
So 74705-62-7 is a valid CAS Registry Number.

Photochemistry of Arylbutadienes. Part 2. Preparation and Photochemistry of 1-(Substituted-aryl)butadienes. A Ground-state Substituent Effect on an Excited-state Reaction

Baldry, Peter J.

, p. 805 - 808 (2007/10/02)

Yields and quantum yields are reported for the photoaddition of methanol to 1-phenylbutadiene and eight substituted 1-phenylbutadienes.For allyl and homoallyl products log Φ correlates more satisfactorily with ground-state substituent constants than with excited-state constants; for cyclopropylmethyl products, no correlation is observed with either set of constants.
