Check Digit Verification of cas no
The CAS Registry Mumber 20919-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,1 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 20919-99:
(7*2)+(6*0)+(5*9)+(4*1)+(3*9)+(2*9)+(1*9)=117
117 % 10 = 7
So 20919-99-7 is a valid CAS Registry Number.
