Check Digit Verification of cas no

The CAS Registry Mumber 201804-42-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 201804-42:
(8*2)+(7*0)+(6*1)+(5*8)+(4*0)+(3*4)+(2*4)+(1*2)=84
84 % 10 = 4
So 201804-42-4 is a valid CAS Registry Number.

Chemoenzymatic synthesis of asymmetrized bis(hydroxymethyl)propanoates (BHYMP*) as a new family of chiral building blocks

Banfi, Luca,Basso, Andrea,Guanti, Giuseppe,Zannetti, Maria Teresa

, p. 4079 - 4088 (1997)

A series of asymmetrized bis(hydroxymethyl)propanoates (BHYMP*) has been prepared in both enantiomeric forms through a chemoenzymatic methodology involving complementary diacetate monohydrolyses and diol monoacetylations catalyzed by lipases.
