70442-01-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70442-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,4,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70442-01:
(7*7)+(6*0)+(5*4)+(4*4)+(3*2)+(2*0)+(1*1)=92
92 % 10 = 2
So 70442-01-2 is a valid CAS Registry Number.
