Check Digit Verification of cas no
The CAS Registry Mumber 158531-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,3 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 158531-13:
(8*1)+(7*5)+(6*8)+(5*5)+(4*3)+(3*1)+(2*1)+(1*3)=136
136 % 10 = 6
So 158531-13-6 is a valid CAS Registry Number.
