155627-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155627-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,2 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155627-34:
(8*1)+(7*5)+(6*5)+(5*6)+(4*2)+(3*7)+(2*3)+(1*4)=142
142 % 10 = 2
So 155627-34-2 is a valid CAS Registry Number.
