Check Digit Verification of cas no
The CAS Registry Mumber 5850-13-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5850-13:
(6*5)+(5*8)+(4*5)+(3*0)+(2*1)+(1*3)=95
95 % 10 = 5
So 5850-13-5 is a valid CAS Registry Number.
