1374993-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374993-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,9,9 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1374993-31:
(9*1)+(8*3)+(7*7)+(6*4)+(5*9)+(4*9)+(3*3)+(2*3)+(1*1)=203
203 % 10 = 3
So 1374993-31-3 is a valid CAS Registry Number.
