Check Digit Verification of cas no
The CAS Registry Mumber 1277101-72-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,7,1,0 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1277101-72:
(9*1)+(8*2)+(7*7)+(6*7)+(5*1)+(4*0)+(3*1)+(2*7)+(1*2)=140
140 % 10 = 0
So 1277101-72-0 is a valid CAS Registry Number.
