Check Digit Verification of cas no
The CAS Registry Mumber 1172-78-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1172-78:
(6*1)+(5*1)+(4*7)+(3*2)+(2*7)+(1*8)=67
67 % 10 = 7
So 1172-78-7 is a valid CAS Registry Number.
