1291076-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1291076-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,7 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1291076-17:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*7)+(3*6)+(2*1)+(1*7)=149
149 % 10 = 9
So 1291076-17-9 is a valid CAS Registry Number.
