Check Digit Verification of cas no
The CAS Registry Mumber 6370-08-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6370-08:
(6*6)+(5*3)+(4*7)+(3*0)+(2*0)+(1*8)=87
87 % 10 = 7
So 6370-08-7 is a valid CAS Registry Number.
