Check Digit Verification of cas no
The CAS Registry Mumber 151221-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,2,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 151221-02:
(8*1)+(7*5)+(6*1)+(5*2)+(4*2)+(3*1)+(2*0)+(1*2)=72
72 % 10 = 2
So 151221-02-2 is a valid CAS Registry Number.
