Check Digit Verification of cas no
The CAS Registry Mumber 1930-72-9 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 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1930-72:
(6*1)+(5*9)+(4*3)+(3*0)+(2*7)+(1*2)=79
79 % 10 = 9
So 1930-72-9 is a valid CAS Registry Number.
