1377804-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1377804-25-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,8,0 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1377804-25:
(9*1)+(8*3)+(7*7)+(6*7)+(5*8)+(4*0)+(3*4)+(2*2)+(1*5)=185
185 % 10 = 5
So 1377804-25-5 is a valid CAS Registry Number.
