Check Digit Verification of cas no
The CAS Registry Mumber 94743-01-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,7,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94743-01:
(7*9)+(6*4)+(5*7)+(4*4)+(3*3)+(2*0)+(1*1)=148
148 % 10 = 8
So 94743-01-8 is a valid CAS Registry Number.
