Check Digit Verification of cas no
The CAS Registry Mumber 94442-10-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,4 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94442-10:
(7*9)+(6*4)+(5*4)+(4*4)+(3*2)+(2*1)+(1*0)=131
131 % 10 = 1
So 94442-10-1 is a valid CAS Registry Number.
