Check Digit Verification of cas no
The CAS Registry Mumber 136308-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,0 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136308-22:
(8*1)+(7*3)+(6*6)+(5*3)+(4*0)+(3*8)+(2*2)+(1*2)=110
110 % 10 = 0
So 136308-22-0 is a valid CAS Registry Number.
