Check Digit Verification of cas no
The CAS Registry Mumber 216481-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,4,8 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 216481-23:
(8*2)+(7*1)+(6*6)+(5*4)+(4*8)+(3*1)+(2*2)+(1*3)=121
121 % 10 = 1
