Check Digit Verification of cas no
The CAS Registry Mumber 1314227-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,2,2 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1314227-72:
(9*1)+(8*3)+(7*1)+(6*4)+(5*2)+(4*2)+(3*7)+(2*7)+(1*2)=119
119 % 10 = 9
So 1314227-72-9 is a valid CAS Registry Number.
