Check Digit Verification of cas no
The CAS Registry Mumber 1934-20-9 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 1934-20:
(6*1)+(5*9)+(4*3)+(3*4)+(2*2)+(1*0)=79
79 % 10 = 9
So 1934-20-9 is a valid CAS Registry Number.
