Check Digit Verification of cas no
The CAS Registry Mumber 1337913-78-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,9,1 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1337913-78:
(9*1)+(8*3)+(7*3)+(6*7)+(5*9)+(4*1)+(3*3)+(2*7)+(1*8)=176
