371773-42-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 371773-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,1,7,7 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 371773-42:
(8*3)+(7*7)+(6*1)+(5*7)+(4*7)+(3*3)+(2*4)+(1*2)=161
161 % 10 = 1
So 371773-42-1 is a valid CAS Registry Number.
