1312583-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312583-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,5,8 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1312583-33:
(9*1)+(8*3)+(7*1)+(6*2)+(5*5)+(4*8)+(3*3)+(2*3)+(1*3)=127
127 % 10 = 7
So 1312583-33-7 is a valid CAS Registry Number.
