1352039-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1352039-70-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,0,3 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1352039-70:
(9*1)+(8*3)+(7*5)+(6*2)+(5*0)+(4*3)+(3*9)+(2*7)+(1*0)=133
133 % 10 = 3
So 1352039-70-3 is a valid CAS Registry Number.
