Check Digit Verification of cas no
The CAS Registry Mumber 1290540-92-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,5,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1290540-92:
(9*1)+(8*2)+(7*9)+(6*0)+(5*5)+(4*4)+(3*0)+(2*9)+(1*2)=149
149 % 10 = 9
