Check Digit Verification of cas no
The CAS Registry Mumber 137283-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,8 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137283-34:
(8*1)+(7*3)+(6*7)+(5*2)+(4*8)+(3*3)+(2*3)+(1*4)=132
132 % 10 = 2
So 137283-34-2 is a valid CAS Registry Number.
