Check Digit Verification of cas no
The CAS Registry Mumber 89433-35-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,3 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89433-35:
(7*8)+(6*9)+(5*4)+(4*3)+(3*3)+(2*3)+(1*5)=162
