749-18-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 749-18-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 749-18:
(5*7)+(4*4)+(3*9)+(2*1)+(1*8)=88
88 % 10 = 8
So 749-18-8 is a valid CAS Registry Number.
