Check Digit Verification of cas no
The CAS Registry Mumber 1934-22-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,3 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1934-22:
(6*1)+(5*9)+(4*3)+(3*4)+(2*2)+(1*2)=81
81 % 10 = 1
So 1934-22-1 is a valid CAS Registry Number.
