640273-55-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 640273-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,7 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 640273-55:
(8*6)+(7*4)+(6*0)+(5*2)+(4*7)+(3*3)+(2*5)+(1*5)=138
138 % 10 = 8
So 640273-55-8 is a valid CAS Registry Number.
