Check Digit Verification of cas no
The CAS Registry Mumber 70900-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,0 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70900-20:
(7*7)+(6*0)+(5*9)+(4*0)+(3*0)+(2*2)+(1*0)=98
98 % 10 = 8
So 70900-20-8 is a valid CAS Registry Number.
