1374781-94-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374781-94-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,7,8 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1374781-94:
(9*1)+(8*3)+(7*7)+(6*4)+(5*7)+(4*8)+(3*1)+(2*9)+(1*4)=198
198 % 10 = 8
So 1374781-94-8 is a valid CAS Registry Number.
