Check Digit Verification of cas no
The CAS Registry Mumber 201791-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201791-69:
(8*2)+(7*0)+(6*1)+(5*7)+(4*9)+(3*1)+(2*6)+(1*9)=117
117 % 10 = 7
So 201791-69-7 is a valid CAS Registry Number.
