Check Digit Verification of cas no
The CAS Registry Mumber 211516-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,5,1 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 211516-63:
(8*2)+(7*1)+(6*1)+(5*5)+(4*1)+(3*6)+(2*6)+(1*3)=91
91 % 10 = 1
So 211516-63-1 is a valid CAS Registry Number.
