Check Digit Verification of cas no
The CAS Registry Mumber 1921-72-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,2 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1921-72:
(6*1)+(5*9)+(4*2)+(3*1)+(2*7)+(1*2)=78
78 % 10 = 8
So 1921-72-8 is a valid CAS Registry Number.
