Check Digit Verification of cas no
The CAS Registry Mumber 121878-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,7 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121878-73:
(8*1)+(7*2)+(6*1)+(5*8)+(4*7)+(3*8)+(2*7)+(1*3)=137
137 % 10 = 7
So 121878-73-7 is a valid CAS Registry Number.
