855749-05-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 855749-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,7,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 855749-05:
(8*8)+(7*5)+(6*5)+(5*7)+(4*4)+(3*9)+(2*0)+(1*5)=212
212 % 10 = 2
So 855749-05-2 is a valid CAS Registry Number.
