Check Digit Verification of cas no
The CAS Registry Mumber 773873-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,8,7 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 773873-26:
(8*7)+(7*7)+(6*3)+(5*8)+(4*7)+(3*3)+(2*2)+(1*6)=210
210 % 10 = 0
So 773873-26-0 is a valid CAS Registry Number.
