1009317-41-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1009317-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,9,3,1 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1009317-41:
(9*1)+(8*0)+(7*0)+(6*9)+(5*3)+(4*1)+(3*7)+(2*4)+(1*1)=112
112 % 10 = 2
So 1009317-41-2 is a valid CAS Registry Number.
