70291-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70291-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,9 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70291-20:
(7*7)+(6*0)+(5*2)+(4*9)+(3*1)+(2*2)+(1*0)=102
102 % 10 = 2
So 70291-20-2 is a valid CAS Registry Number.
