Check Digit Verification of cas no
The CAS Registry Mumber 70224-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,2 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70224-83:
(7*7)+(6*0)+(5*2)+(4*2)+(3*4)+(2*8)+(1*3)=98
98 % 10 = 8
So 70224-83-8 is a valid CAS Registry Number.
