Check Digit Verification of cas no
The CAS Registry Mumber 137559-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,5 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137559-35:
(8*1)+(7*3)+(6*7)+(5*5)+(4*5)+(3*9)+(2*3)+(1*5)=154
154 % 10 = 4
So 137559-35-4 is a valid CAS Registry Number.
