1312236-47-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312236-47-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,2,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1312236-47:
(9*1)+(8*3)+(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*4)+(1*7)=107
107 % 10 = 7
So 1312236-47-7 is a valid CAS Registry Number.
