1374543-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374543-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,5,4 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1374543-21:
(9*1)+(8*3)+(7*7)+(6*4)+(5*5)+(4*4)+(3*3)+(2*2)+(1*1)=161
161 % 10 = 1
So 1374543-21-1 is a valid CAS Registry Number.
