Check Digit Verification of cas no
The CAS Registry Mumber 191917-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,9,1 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 191917-30:
(8*1)+(7*9)+(6*1)+(5*9)+(4*1)+(3*7)+(2*3)+(1*0)=153
153 % 10 = 3
So 191917-30-3 is a valid CAS Registry Number.
