Check Digit Verification of cas no
The CAS Registry Mumber 1331786-73-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,1,7,8 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1331786-73:
(9*1)+(8*3)+(7*3)+(6*1)+(5*7)+(4*8)+(3*6)+(2*7)+(1*3)=162
162 % 10 = 2
So 1331786-73-2 is a valid CAS Registry Number.
