Check Digit Verification of cas no
The CAS Registry Mumber 943964-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,9,6 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 943964-12:
(8*9)+(7*4)+(6*3)+(5*9)+(4*6)+(3*4)+(2*1)+(1*2)=203
203 % 10 = 3
So 943964-12-3 is a valid CAS Registry Number.
