1374993-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374993-56-2 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, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1374993-56:
(9*1)+(8*3)+(7*7)+(6*4)+(5*9)+(4*9)+(3*3)+(2*5)+(1*6)=212
212 % 10 = 2
So 1374993-56-2 is a valid CAS Registry Number.
