Check Digit Verification of cas no
The CAS Registry Mumber 1249-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1249-67:
(6*1)+(5*2)+(4*4)+(3*9)+(2*6)+(1*7)=78
78 % 10 = 8
So 1249-67-8 is a valid CAS Registry Number.
