Check Digit Verification of cas no
The CAS Registry Mumber 1419778-17-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,9,7,7 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1419778-17:
(9*1)+(8*4)+(7*1)+(6*9)+(5*7)+(4*7)+(3*8)+(2*1)+(1*7)=198
