433692-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 433692-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,6,9 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 433692-91:
(8*4)+(7*3)+(6*3)+(5*6)+(4*9)+(3*2)+(2*9)+(1*1)=162
162 % 10 = 2
So 433692-91-2 is a valid CAS Registry Number.
