209070-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209070-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,0,7 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 209070-38:
(8*2)+(7*0)+(6*9)+(5*0)+(4*7)+(3*0)+(2*3)+(1*8)=112
112 % 10 = 2
So 209070-38-2 is a valid CAS Registry Number.
