Check Digit Verification of cas no
The CAS Registry Mumber 299-70-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 299-70:
(5*2)+(4*9)+(3*9)+(2*7)+(1*0)=87
87 % 10 = 7
So 299-70-7 is a valid CAS Registry Number.
