1312205-37-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312205-37-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,2,0 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1312205-37:
(9*1)+(8*3)+(7*1)+(6*2)+(5*2)+(4*0)+(3*5)+(2*3)+(1*7)=90
90 % 10 = 0
So 1312205-37-0 is a valid CAS Registry Number.
