1370015-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1370015-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,0,0,1 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1370015-91:
(9*1)+(8*3)+(7*7)+(6*0)+(5*0)+(4*1)+(3*5)+(2*9)+(1*1)=120
120 % 10 = 0
So 1370015-91-0 is a valid CAS Registry Number.
