Check Digit Verification of cas no
The CAS Registry Mumber 643758-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,5 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 643758-65:
(8*6)+(7*4)+(6*3)+(5*7)+(4*5)+(3*8)+(2*6)+(1*5)=190
190 % 10 = 0
