7Check Digit Verification of cas no
The CAS Registry Mumber 12238-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 12238-94:
(7*1)+(6*2)+(5*2)+(4*3)+(3*8)+(2*9)+(1*4)=87
87 % 10 = 7
So 12238-94-7 is a valid CAS Registry Number.
