Check Digit Verification of cas no
The CAS Registry Mumber 119019-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,1 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119019-99:
(8*1)+(7*1)+(6*9)+(5*0)+(4*1)+(3*9)+(2*9)+(1*9)=127
127 % 10 = 7
So 119019-99-7 is a valid CAS Registry Number.
