187938-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187938-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,9,3 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 187938-34:
(8*1)+(7*8)+(6*7)+(5*9)+(4*3)+(3*8)+(2*3)+(1*4)=197
197 % 10 = 7
So 187938-34-7 is a valid CAS Registry Number.
