Check Digit Verification of cas no
The CAS Registry Mumber 1254077-26-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,0,7 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1254077-26:
(9*1)+(8*2)+(7*5)+(6*4)+(5*0)+(4*7)+(3*7)+(2*2)+(1*6)=143
143 % 10 = 3
So 1254077-26-3 is a valid CAS Registry Number.
