Check Digit Verification of cas no
The CAS Registry Mumber 950697-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,0,6,9 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 950697-19:
(8*9)+(7*5)+(6*0)+(5*6)+(4*9)+(3*7)+(2*1)+(1*9)=205
205 % 10 = 5
