1374446-65-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374446-65-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,4,4 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1374446-65:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*4)+(3*6)+(2*6)+(1*5)=177
177 % 10 = 7
So 1374446-65-7 is a valid CAS Registry Number.
