156274-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156274-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,7 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156274-08:
(8*1)+(7*5)+(6*6)+(5*2)+(4*7)+(3*4)+(2*0)+(1*8)=137
137 % 10 = 7
So 156274-08-7 is a valid CAS Registry Number.
