123994-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123994-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,9 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123994-64:
(8*1)+(7*2)+(6*3)+(5*9)+(4*9)+(3*4)+(2*6)+(1*4)=149
149 % 10 = 9
So 123994-64-9 is a valid CAS Registry Number.
