Check Digit Verification of cas no
The CAS Registry Mumber 1374123-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,1,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1374123-09:
(9*1)+(8*3)+(7*7)+(6*4)+(5*1)+(4*2)+(3*3)+(2*0)+(1*9)=137
