1312701-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312701-47-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,7,0 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1312701-47:
(9*1)+(8*3)+(7*1)+(6*2)+(5*7)+(4*0)+(3*1)+(2*4)+(1*7)=105
105 % 10 = 5
So 1312701-47-5 is a valid CAS Registry Number.
