Check Digit Verification of cas no
The CAS Registry Mumber 209624-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,6,2 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 209624-07:
(8*2)+(7*0)+(6*9)+(5*6)+(4*2)+(3*4)+(2*0)+(1*7)=127
127 % 10 = 7
So 209624-07-7 is a valid CAS Registry Number.
