Check Digit Verification of cas no
The CAS Registry Mumber 171613-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,6,1 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 171613-35:
(8*1)+(7*7)+(6*1)+(5*6)+(4*1)+(3*3)+(2*3)+(1*5)=117
