Check Digit Verification of cas no
The CAS Registry Mumber 137170-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,7 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137170-80:
(8*1)+(7*3)+(6*7)+(5*1)+(4*7)+(3*0)+(2*8)+(1*0)=120
120 % 10 = 0
So 137170-80-0 is a valid CAS Registry Number.
