Check Digit Verification of cas no
The CAS Registry Mumber 19404-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,0 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19404-12:
(7*1)+(6*9)+(5*4)+(4*0)+(3*4)+(2*1)+(1*2)=97
97 % 10 = 7
So 19404-12-7 is a valid CAS Registry Number.
