Check Digit Verification of cas no
The CAS Registry Mumber 204574-94-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,7 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 204574-94:
(8*2)+(7*0)+(6*4)+(5*5)+(4*7)+(3*4)+(2*9)+(1*4)=127
127 % 10 = 7
So 204574-94-7 is a valid CAS Registry Number.
