Check Digit Verification of cas no
The CAS Registry Mumber 1222406-76-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,4,0 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1222406-76:
(9*1)+(8*2)+(7*2)+(6*2)+(5*4)+(4*0)+(3*6)+(2*7)+(1*6)=109
109 % 10 = 9
