Check Digit Verification of cas no
The CAS Registry Mumber 222615-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,6,1 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 222615-12:
(8*2)+(7*2)+(6*2)+(5*6)+(4*1)+(3*5)+(2*1)+(1*2)=95
95 % 10 = 5
So 222615-12-5 is a valid CAS Registry Number.
