Check Digit Verification of cas no
The CAS Registry Mumber 278176-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,8,1,7 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 278176-08:
(8*2)+(7*7)+(6*8)+(5*1)+(4*7)+(3*6)+(2*0)+(1*8)=172
172 % 10 = 2
So 278176-08-2 is a valid CAS Registry Number.
