Check Digit Verification of cas no
The CAS Registry Mumber 163215-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,2,1 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 163215-15:
(8*1)+(7*6)+(6*3)+(5*2)+(4*1)+(3*5)+(2*1)+(1*5)=104
104 % 10 = 4
So 163215-15-4 is a valid CAS Registry Number.
