Check Digit Verification of cas no
The CAS Registry Mumber 1187649-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,6,4 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1187649-33:
(9*1)+(8*1)+(7*8)+(6*7)+(5*6)+(4*4)+(3*9)+(2*3)+(1*3)=197
