Check Digit Verification of cas no
The CAS Registry Mumber 219931-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219931-68:
(8*2)+(7*1)+(6*9)+(5*9)+(4*3)+(3*1)+(2*6)+(1*8)=157
157 % 10 = 7
So 219931-68-7 is a valid CAS Registry Number.
