Check Digit Verification of cas no
The CAS Registry Mumber 21742-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,4 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21742-26:
(7*2)+(6*1)+(5*7)+(4*4)+(3*2)+(2*2)+(1*6)=87
87 % 10 = 7
So 21742-26-7 is a valid CAS Registry Number.
