Check Digit Verification of cas no
The CAS Registry Mumber 156222-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156222-44:
(8*1)+(7*5)+(6*6)+(5*2)+(4*2)+(3*2)+(2*4)+(1*4)=115
115 % 10 = 5
So 156222-44-5 is a valid CAS Registry Number.
